The reducing conditions and the solubilization of nodules have been simulated in a bench scale process. The concentrations of a number of minor components have been determined at each stage of the process in an attempt to understand the chemical reactions that occur between these minor components and the reagents that were used. Thirty-seven elements were identified in the ferromanganese nodules by the proton induced X-ray emission technique. The technique, which is described, can be used to follow the distribution of all these elements in the various solid and liquid phases in the flow diagram. Although the main concern in this work has been in following the distribution of Cu, Ni, Co, Fe and Mn in the various phases in the separation scheme, the utility of a multielemental analytical technique such as proton induced X-ray emission spectroscopy for following the distribution of the elements of interest at various stages in the separation scheme was demonstrated.
